Advent of new imaging modalities such as computed tomography, magnetic resonance imaging and ultrasound contributed greately to the specific imaging diagnosis. However plain chest X-ray is still most prequently used for imaging diagnosis of respiratory disease in clinical pratic and it is important to make a good quality of X-ray film and good interpretation. The optimal chest X-ray should be taken with full inspiration without rotation and motion and the exposure is at the level of barely demonstrable thoracic vertebral disc space. It is recommended that higk KVP technique for detection of lesions which is overlaped by mediastinum, heart and rib cage. It is better to examine chest X-ray film start at some distance(6-8 feet) and closer to the film later on and the reader should not read a film in fatigue condition. The reading room should be quiet and relately dark illumination. It is important, to make a good X-ray film and good interpretation to reduce the observer error.

The purpose of this study was to investigate gender differences in behavioral characteristics and their awareness of obese school children. The results were as follows 1. In comparison with eating habits and food preference, the girls had more irregular breakfast and were likely to have vegetables / fruits than the boys. 2. In characteristics related to exercise and activities, boys did more exercise than girls. Particularly, in lunch free time, boys participated in playing various active excercise with friends, but girls participated in more non-active behaviors (such as, chattering, reading, or playing jack-stones). 3. In comparison with their awareness related to obese persons, about a half of boys had positive opinions (e. grong, healthy.), but about only 20% of girls had positive opinions.

It is the new promising method of obtaining the information about the state of a surface of a solid body, thin and multilayer structures. An idea of the method consists in reading and analyzing the relations U(t), dU/dt(t), dU/dt(U) on an electrical cell when anodizing an investigated object. By these relation it is possible to control the presence of impurities in the metal on the path of the anodization front, a structure and characteristics of the object being oxidized as well as of an oxide which is being formed during anodizing, the change in composition of the oxide layer, the thickness and composition of metallic and dielectric layers being a part of the layers boundaries.

This paper compares the French Gustave Flaubert (1821-1880) and the Vietnamese Vũ Trọng Phụng (1912-1939), and explores transformations of their aesthetic experiences that led to the autonomization of French literary field in the nineteenth century and Vietnamese in the early twentieth century. Inspired from the term "archive" coined by Michel Foucault, this article argues that Flaubert, in abandoning the bourgeois tastes, contested realism and built his own writing ideology and style, which is called subjective realism. On the other hand, it also argues that Vũ Trọng Phụng, through the popular report genre, he gained success and evolved his own novel writing style, aptly called the realism of speech. It is ostensible that the transformation in the two authors' writing style and aesthetic experience was derived from the way they distanced themselves from their contemporaries' common tastes while making use of free indirect speeches, all with the aim of granting readers the autonomy of reading.

Both the late 15th-century Unicorn Tapestries now at the Cloisters Museum in New York and Daesoon Jinrihoe's Simudo Paintings present a religious narrative through the symbol of the search for an animal that is then subdued. This is now the prevailing scholarly interpretation of the New York Unicorn Tapestries, with the unicorn representing Jesus Christ, although a concurrent reading alluding to human love cannot be excluded. The article examines the New York Unicorn Tapestries according to their Christological interpretation, rooted in traditions about the unicorn popularized by the German medieval mystic Hildegard of Bingen, although in fact much older. It then discusses the Buddhist iconographic tradition of ox-herding paintings that represents an antecedent for the Simudo Paintings and notes the latter's differences and similarities with the New York Unicorn Tapestries.

Purpose: The aim of this study was to assess the ex vivo diagnostic ability of 9 different cone-beam computed tomography (CBCT) settings in the detection of recurrent caries under amalgam restorations in primary teeth. Materials and Methods: Fifty-two primary teeth were used. Twenty-six teeth had dentine caries and 26 teeth did not have dentine caries. Black class II cavities were prepared and restored with amalgam. In the 26 carious teeth, recurrent caries were left under restorations. The other 26 intact teeth that did not have caries served as controls. Teeth were imaged using a $100{\times}90-mm$ field of view and a 0.2-mm voxel size with 9 different CBCT settings. Four observers assessed the images using a 5-point scale. Kappa values were calculated to assess observer agreement. CBCT settings were compared with the gold standard using a receiver operating characteristic analysis. The area under the curve (AUC) values for each setting were compared using the chi-square test, with a significance level of ${\alpha}=.05$. Results: Intraobserver kappa values ranged from 0.366 to 0.664 for observer 1, from 0.311 to 0.447 for observer 2, from 0.597 to 1.000 for observer 3, and from 0.869 to 1 for observer 4. Furthermore, interobserver kappa values among the observers ranged from 0.133 to 0.814 for the first reading and from 0.197 to 0.805 for the second reading. The highest AUC values were found for setting 5 (0.5916) and setting 3 (0.5886), and were not found to be statistically significant(P>.05). Conclusion: Variations in tube voltage and tube current did not affect the detection of recurrent caries under amalgam restorations in primary teeth.

Purpose : The aim of this study was to evaluate the effect of liquid crystal display (LCD) monitor type and observer experience on the diagnostic performance in soft-copy interpretations of maxillary sinus inflammatory lesions on panoramic radiographs. Materials and Methods : Ninety maxillary sinuses on panoramic images were grouped into negative and positive groups according to the presence of inflammatory lesions, using CT for confirmation. Monochrome and color LCDs were used. Six observers participated and ROC analysis was performed to evaluate the diagnostic performance. The reading time, fatigue score, and inter-/intra-observer agreements were assessed. Results : The interpretation of maxillary sinus inflammatory lesions was affected by the LCD monitor type used and by the experience of the observer. The reading time was not significantly different, however the fatigue score was significantly different between two LCD monitors. Inter-observer agreement was relatively good in experienced observers, while the intra-observer agreement for all observers was good with monochrome LCD but not with color LCD. Conclusion : The less experienced observers showed lowered diagnostic ability with a general color LCD.

Purpose: The goal of this systematic review was to compare the use of cone-beam computed tomography (CBCT) with that of computed tomography (CT) for volumetric evaluations of the tongue and oral cavity. Materials and Methods: A search for articles was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. The PubMed, Scopus, ScienceDirect, and SAGE Journals databases were searched for articles published between 2011 and 2021. Articles were screened and assessed for eligibility. Screening involved checking for duplication, reading the title and abstract, and reading the full text. Results: The initial search retrieved 25,780 articles. Application of the eligibility criteria yielded 16 articles for qualitative analysis. Multiple uses of CBCT were identified. In several studies, researchers assessed the volumetric correlation between tongue and oral cavity volumes, as well as other parameters. Post-treatment volumetric evaluations of the oral cavity were also reported, and the reliability of CBCT was assessed. The use of CT resembled that of CBCT. Conclusion: CBCT has been used in the evaluation of tongue and oral cavity volumes to assess correlations between those volumes and with the upper airway. It has also been used for volumetric evaluation after surgical and nonsurgical procedures and to assess the relationships between tongue volume, tooth position, occlusion, and body mass index. Participants with obstructive sleep apnea and malocclusion have been evaluated, and the reliability of CBCT has been assessed. In the included studies, CT was utilized for similar purposes as CBCT, but its reliability was not assessed.
